Hy-Pro 4.5 L/min 12 / 24vDC Constant Running Pump

The versatile PC constant running power units use a heavy-duty fan cooled motor driving pump to provide outputs of up to 3.0L/min.

For use in heavy duty applications on larger yachts or commercial craft these units come fitted with pressure compensated flow controls, relief valves and cylinder lock valves as standard. Developed specifically for marine autopilot applications in the commercial and larger pleasure boat market the PC pumps can be used with single or twin ram systems.

The units are designed to be compatible with both balanced and unbalanced rams and pressurised reservoir type systems.

These robust heavy duty pumps are particularly popular with commercial craft, such as fishing boats, where power and long life are important.
